GetGeometryClassEx

Returns non-zero if the owlClass is a geometry type. This call will return the input class
for all classes initially available. It will return as well non-for all classes created by the
user or loaded / imported through a model that (indirectly) inherit one of the
original classes available. in this case it returns the original available class
it inherits the behavior from.

This call has the same behavior as GetGeometryClass, however needs to be
used in case classes are exchanged as a successive series of integers.

Property model

Size: 64 bit / 8 byte (value)
The handle to the model. The model handle is static during its existance. Several models can be opened simultaniously within one session. Different models are always independent, threads are allowed to be running on different models simultaniously.

Property owlClass

Size: 64 bit / 8 byte (value)
This attribute represents a handle to the class. The term owl is comming from W3C, the classes follow the expression power of Semantic Web concepts, therefore classes support multiple inheritance. Technically classes can also be distributed over different resources, however for this the parametric library is required as an extension on the basic Geometry Kernel API.
